Abstract
The utility model discloses a kind of slip ring inner hole of spindle processing tools, including the housing for wrapping up slip ring main shaft workpiece, and are tightly attached to the clamping centrum of outer casing inner wall；Housing bottom end be provided with for by housing, clamp centrum and slip ring main shaft Workpiece clamping binding nut；The first bolt hole is offered in the top sidewall of housing, the bottom insertion of interior the first bolt inserted with diameter less than the first bolt hole of the first bolt hole, the first bolt clamps centrum；The second bolt hole is offered in the middle part of sliding channel of housing, and the second bolt is provided in the second bolt hole；Third bolt hole is offered in the bottom sidewall of housing, is less than the third bolt of third bolt hole in third bolt hole inserted with diameter, and the bottom insertion of third bolt clamps centrum；The top of first bolt and the second bolt is connected by spring.This tooling only needs to unscrew binding nut to workpiece uniform force, and during releasing and clamping, very easy.
Description
Technical field
The present invention relates to a kind of for fixing the tooling of workpiece, more specifically to one kind for fixing slip ring main shaft
Workpiece and the tooling for being used to carry out interior hole machined.
Background technique
It in the prior art, is by slip ring main shaft workpiece in housing, so for the interior hole machined of slip ring main shaft workpiece
Clamping is carried out by eight mandrils afterwards, but since the contact of mandril is point contact, dynamics cannot be completely the same, after causing processing
Slip ring main shaft internal diameter due to unbalance stress generate deformation of products, influence product quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of slip ring inner hole of spindle processing tools, can
In order to achieve the above object, the present invention takes following technical scheme: a kind of slip ring inner hole of spindle processing tool, including
For wrapping up the housing of slip ring main shaft workpiece, and it is close to be set to outer casing inner wall and slip ring main shaft (with being both close to below)
Clamping centrum between workpiece outer wall；Housing bottom end be provided with for by housing, clamp centrum and slip ring main shaft Workpiece clamping
Binding nut；
The first bolt hole is offered in the top sidewall of housing, inserted with diameter less than the first bolt hole in the first bolt hole
The first bolt, the first bolt bottom insertion clamp centrum；
Offer the second bolt hole in the middle part of sliding channel of housing, in the second bolt hole inserted with the second diameter of bolt hole phase
The second same bolt；
Third bolt hole is offered in the bottom sidewall of housing, third bolt hole is interior to be less than third bolt hole inserted with diameter
Third bolt, the bottom of third bolt be also inserted into clamp centrum；
The top of first bolt and the second bolt is connected by spring.
Under preferred embodiment, the top of housing is also provided with packing bolt hole；It can be by the tooling by the packing bolt hole
It is connected on the packing of lathe spindle.
Under preferred embodiment, spring is tension spring, i.e., only applies pulling force.
It is an advantage of the current invention that the inner wall for clamping centrum is tightly attached to slip ring main shaft workpiece, so that stress is uniform
, therefore be in process not in the case where unbalance stress mentioned in background technique generates deformation of products.Except this it
Outside, it only needs to unscrew binding nut when releasing clamping, the pulling force of spring will will clamp centrum and pull toward the direction of binding nut, just
Slip ring main shaft workpiece can be made to be detached from clamped condition.
Detailed description of the invention
Fig. 1 is equipped with the sectional view of the tooling of slip ring main shaft workpiece；
Fig. 2 is the schematic diagram of slip ring main shaft workpiece in figure one.
Specific embodiment
A specific embodiment of the invention is described with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of slip ring inner hole of spindle processing tool of the present invention, including for wrapping up slip ring main shaft work
The housing 2 of part 1, and it is tightly attached to the clamping centrum 3 of 2 inner wall of housing；2 bottom end of housing be provided with for by housing 2, clamp centrum
3 and slip ring main shaft workpiece 1 clamp binding nut 4；(bottom end mentioned here is the bottom end direction of slip ring main shaft workpiece 1, that is, is schemed
In right direction, behind mention top or top when is then opposite direction, i.e. left direction in figure is only for convenient
Description)
The first bolt hole 51 is offered in the top sidewall of housing 2, inserted with diameter less than first in the first bolt hole 51
The bottom insertion of first bolt 511 of bolt hole 51, the first bolt 511 clamps centrum 3；
Offer the second bolt hole 52 in the middle part of sliding channel of housing 2, in the second bolt hole 52 inserted with the second bolt hole
Identical second bolt 521 of 52 diameters；
Third bolt hole 53 is offered in the bottom sidewall of housing 2, third bolt hole 53 is interior to be less than third inserted with diameter
The bottom insertion of the third bolt 531 of bolt hole 53, third bolt 531 clamps centrum 3；
First bolt 511 is connected with the top of the second bolt 521 by spring 6；Spring 6 is tension spring, i.e., only applies and draw
Power.
The top of housing 2 is also provided with packing bolt hole 7, so as to be connected the tooling by the packing bolt hole 7
Onto packing.
It is clamped in centrum 3 in use, slip ring main shaft workpiece 1 is installed to, then makes to clamp vertebra by screwing binding nut 4
Then body 3 and housing 2 are processed the inner hole of slip ring main shaft workpiece 1 by interaction force clamping slip ring main shaft workpiece 1.
By unscrewing binding nut 4 (reserve gap under binding nut 4 at this time and be inserted for subsequent clamping centrum 3), and pass through
The pulling force of spring 6 will clamp centrum 3 and pull toward the direction of binding nut 4, so that it may so that slip ring main shaft workpiece 1, which is detached from, clamps shape
State.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
